Audison AV 12 D2/D4 II - 12-inch Subwoofer with Variable Impedance for Precise Bass
The Audison AV 12 D2/D4 II is a 12-inch (30 cm) subwoofer that delivers controlled, powerful bass in compact enclosures. With 550 W continuous power and 1100 W peak, it performs reliably, while the dual voice coils in D2 (2+2 Ohm) or D4 (4+4 Ohm) allow for flexible wiring. An aluminum chassis, ferrite magnet, and a robust polypropylene cone ensure stability and consistent performance. Its frequency response of 25 to 400 Hz and a sensitivity of 84.5 dB are well-suited for systems that value clean low-frequency reproduction. A bass-reflex enclosure of at least 21 liters, tuned to 45 Hz, is recommended.
